In April, CRF Frozen Foods issued a voluntary recall of 358 frozen fruit and vegetable products over Listeria concerns. The original recall affected national chains like Trader Joe's, Safeway, and Costco, and contaminated products included everything from organic to non-organic varieties of strawberries, broccoli, cauliflower, and stir-fry blends. Earlier this week, The National Frozen Foods Corporation announced that this same recall has now grown to include not-ready-to-eat frozen fruit and vegetable products distributed at Target and Walmart.

The original recall stemmed from CRF's Pasco, WA facility, who distributed contaminated products to grocery chains in all 50 states and several Canadian provinces. The Food And Drug Administration reports that products currently being recalled at Target and Walmart include frozen peas and mixed vegetables that were originally sold between September 2, 2015 and June 2, 2016. Thankfully, there have not yet been any reported illnesses due to any items that were sold at Target or Walmart.

If you think you may have a contaminated product, there are a couple things you should look for. Affected products will have a sell-by date between April 26, 2016 and April 26, 2018. You can find the full list of product UPC codes sold at every chain—including Trader Joe's, Safeway, and Costco—here, and the list of contaminated products specifically sold at Target and Walmart here.

If you find or think that you have a contaminated product, do not eat it. You should either throw it away, or return it to the store for a full refund. If you have additional questions regarding your product, you should call the National Frozen Foods Corporation consumer hotline at 1-800-253-8269.

This is not the first Listeria outbreak of summer: Earlier this month, select CLIF bars were recalled over similar concerns, and both Whole Foods and Starbucks have been subject to Listeria recalls in the last year. Listeria mainly affects pregnant women, newborns, adults over 65, and people with weakened immune systems, but it can affect anyone. Symptoms include fever, diarrhea, weakness, and abdominal pain and can begin to take effect weeks after infection. If you're experiencing any of these symptoms, check in with your general doctor.
